title: [Alternative ways of collateral venous flow in occlusion of superior sagittal sinus].
abstract: The authors demonstrated alternative ways of bloodflow from occluded superior sagittal sinus through hypertrophic dural veins (middle meningeal veins) and sphenoparietal sinus. Parameters of bloodflow were evaluated using triplex ultrasonography. The possibility of venous drainage into anterior segment of superior sagittal sinus proximal to the site of occlusion with further retrograde flow towards dural venous anastomosis is verified. Possibilities of spiral CT-venography and standard time-of-flight MR-venography for assessment of collateral venous flow were estimated.
